Here Some Basic Formulas/Rules Are given below :-

Square Root : If x2 = y, we say that the square root of y is x and we write, √y = x.
Thus, √4 = 2, √9 = 3, √196 =14.
Cube Root : The cube root of a given number x is the number whose cube is x. We denote the cube root of x by 3x
Thus, 38 = 32x 2 x 2 = 2,
and 3343 = 37 X 7 X 7 = 7 etc.
Note :
1. √xy = √x X √y

2. √x/y = x/y = x/y X y/y = xy/y
